.. Hi there.
This is a typical earth problem. Some of the lights use the same earth and when some of the earth points are not good, the power go through the other lights. That is why some lights go's faster, it's all about resistants. Check all the earth points in the light holders and under the dash and also between the battery, engine and body. Good luck.
Whilst diagnosing the problem it would be best to put the old flasher unit back in . There might be two problems here : firstly the cause of a flasher circuit blinking rapid is usually a blown bulb ( or wrong bulb ) . Secondly the reason why another circuit would start to operate when operating the flasher circuit is usually caused by a bad earth somewhere so that an alternative earth is achieved through another circuit .
Perhaps you should check the LH indicator bulbs and then check and clean all your earths .
Tip : you can use a little jumper wire to by pass the original earths and keep tracing until the circuit functions normally .
I hope this helps
Thanks "Pit Crew" I will try this as soon as possible and will post a result. I have never changed the bulbs in the 7 years that I owned this Dodge. At first I thought it was the bulbs as well, but when flashing both front and rear are flashing at the same brightness as the right side. I will check anyway in case a bulb may now be faulty. It makes sense that the lights being on constantly would be the cause of it being grounded somewhere, but why only when I install the NEW flasher and yet it operates correctly with the OLD unit installed. If it were grounding out somewhere, wouldn't it be "on" when either flasher was plugged in? Anyway I will try and see what happens. Thanks again, I really appreciate the insight.
How did you get on ?
